I just purchased 4 of these trays to use under plants in order to keep the custom-built bookcase that runs along my windows from getting wet and dirty. The trays get filled with marble chips or pebbles, and individual pots can go into them without saucers, since the heavy plastic trays are made for the purpose of keeping wood dry.
Plant trays that are large and simple are very hard to find and some are very expensive. I find this a very good and inexpensive solution.
I recently damaged my expensive trunk liner in my Audi. After looking around for another custom liner and failing to find one that wasn't overly priced for what you get, I saw this boot tray at my local Target that fit the bill. For the price it is such a great deal and does the job perfectly. It is a hard plastic with a lip on it so it will work great to keep my trunk clean when lugging stuff around. I have a small trunk so 2 of these in the back fit perfectly. Leave it to Target to offer such an inexpensive solution to my trunk mat problem. Highly recommend this item!
